It extremely frequently happens that the Java source code editor incorrectly models the AST of the source file. (Or something like that, I'm not familiar with the internals.) It usually happens when I type and edit the source quickly. (i.e. typing fastly, using quick assist right away, and basically sending events to the editor in a rapid manner.) In those cases, invoking any refactoring functionality (Generate setters, override methods, quick assistance) results in an error dialog about the document being in an invalid state. In other cases the above refactoring straight up inserts code in an invalid manner. Some example for code: public class MyClass { int myField; //cursor location } When I invoke generate constructor with myField parameter, the resulting code may look similar to this: public class MyClass { int my public MyClass(int myField) { this.myField = myField; }Field; } Which is obviously erroneous. The mark occurrences functionality may highlight invalid parts of the code when such errors happen. This bug have been occurring since forever, and was present in previous versions of Eclipse too. In order to fix it on user side, I usually wait a few sec, insert a tab in somewhere the code, and then invoke the refactoring functionality again, and it will usually work then. I wasn't able to reproduce the bug in a stable manner on small code examples, however, it happens very frequently in larger files.

Looks similar to bug 526097.
This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. -- The automated Eclipse Genie.
